Green AshFraxinus pennsylvanica

This hardy shade tree has been a popular choice due to its fast growth, nice shade, and ability to adapt to a range of soil conditions. Since the onset of Dutch elm disease, the green ash has been heavily used as a replacement for the American elm in urban landscapes across the U.S. Unfortunately, now the green ash is coming under attack by the emerald ash borer, which is spreading across the country.
